Greetings All,
I am earthling from Ai that is trying to reach universal enlightenment. Today I am doing my research on how to make a talk box or a vocoder.
I understand the difficulty in try to do this but i think it would be an interesting project for my style of work.
Here are some websites I am looking into to get this done.
